The autopsy report of Rose Pizem, the four-year-old girl whose body was found in a suitcase in the Yarkon river approximately two months ago, reinforces grandfather Ronnie Ron's first confession, which stated that he was the one who caused the child's death by forcefully slapping her, Army Radio reported on Wednesday. "Death could have been induced by intra-cranial damage such as a head injury or slap across the face. Since children's cranial bones are soft and flexible, liquid can diffuse even when the bones are unbroken," the report from the Abu Kabir Institute of Forensic Medicine reads. The extended time underwater caused advanced decay to the body and made the investigators' work all the more difficult. The report suggested that the body was submerged for a period of over two months. After relating to the police his initial version, Ron retracted his confession. Both he and his wife Marie Pizem, the girl's mother, were indicted on charges of murder, yet the indictment does not specify the time or method, or name either of the suspects as the murderer. It is also unclear from the indictment whether Rose was alive when tossed into the river. The autopsy report does not provide definitive answers to these questions, though it does make various allusions, the station reported. The trial of Marie Pizem and Ronnie Ron is set to begin next week.
